This invention relates to improvements in machines of the type in which the sheets at the back of the book are cut away and which are then secured together by meansl of glue or the like which also serves to hold a cover thereon.

Various means have been suggested for roughening the cut edges of these sheets to make them'receive and hold the glue more firmly. An object of this invention however is to provide means for placing theeut edges of the sheets to one side-so .as toplace them in overlapping relation tol each other and apply- 111g glue to these edges while in this over lapping position. In this way some glue is applied to the sides of the sheets as well as to their edges so that when the v sheets are again brought back to their normal midposition some glue will be found to lie be'- tween the sheets themselves so that a hold is obtained on the sheets along a narrow margin on the faces of the sheets, Whereas, heretofore the sheets came in contact with the glue only solely on their edges.

This and other objects, as will hereinafter appear, are accomplished by this invention which is fully described in the following specication and shown' in the accompanying drawings, in which:

Fig. 2 is a section ofthe same on kthe line 2-2 of Fig. v1; Fig. 3 is a top plan view of a modifedform of the device; and Fig. 4 isa section on thevbroken line 4-4 ofFig. 3.

This invention is an improvement on the book binding machine shown in the atent Se tember 16, 1913, and may be 'similarl thereltb except 1n the particulars which are herein shown and described,

Ther embodiment'illustrated comprises va `chain made up of links 10 which .are pivotnels 13 and 14. The' .10 consist of at 1927. Serial No. 194,949.

plates and opposite of each of these is another vserves to normall press the plates 10 land 15 towardeach ot er.

As the books enter the machine in the form of signatures which are folded in any well known manner, the plate 15 is drawn back compressing the springs 18 so that the books Aconsisting of a bunch of signatures may be inserted. As explained in the above mentioned patent, the spring 18 is then permitted todraw the plate 15 down so'as to grip the book A. The back of the book-A is then cut in any well .this patent and the book then passes to the gluing wheel as shown in Fig. 1". The embodiment lshown* in Figs. land 2 comprises a double wheel 19l having oppositely inclined spiral teeth which are pressed in the form of a herrin -bone ear and which are carried upon a sha t 20 w ich is suitably .journalled in a glue pot 21. -The gear 19 is placed beneath the path of the books A and known manner as explained vin referably with the center of the herringone gear 19 near theecenter of the books A with the shaft20 extending substantially at right angles to the path ofthe books.

The books A and the upperportlon ofthe wheels 19 areadvanced in the same direction and at substantially uniform lrate, but the teeth as shown in, Fig. 2, thereby causing the edges of the sheets to assume an 'overlap ing relation with respect to the adjacent s eets so that a narrow margin of each sheet will be uncovered so that the ones in contact with the glue which 'is picked up by the wheel 19from the mass of'glue B in the bottom of the glue pot 21.

Thus it will be seen that I have provided a sim le and effective means fo/r applying glue to t e narrow overlapping 'margms of sheets so that when these-sheets are again brought back to their normal overlapping position some glue will be carried in between the sheets inv contact with 'the wheel A 35 wheel be narrowerthan that of the "wheel 22 and thereby 'greanyfstregniening the boek because the'she'ets are now glued to each other along narrow margins whereas by the method lheretoforelused' adhesion took place principilly betweenftheedges of the sheets and the gue..

Figs. 3' and 4 show another embodiment of the inventioniin which two-toothedy wheels- 22.and 23 are-carried upon shafts 24 and I25V The of the ,books is shown as C and i the boo s, shown in Fig. 4 as D are held by '20 the late 10F'and 1'5a of the conveyon T e ltoothed lwheels 22 and 23 are preferably provided with straight teeth, these wheels being set at oppositely inclined angles. .AsY the bookgD. passes -across the-top of the 25 toothed whee1'22 the lsheets arev deflected to one side as shown infFig. 4, the wheel in this case/preferably running at a somewhat greater speed thanfthat of the book and carrying glue which. isl picked up from the body of the glue E inthe glue ot 26.

' As shown in Flg.- 4, `the sheets at the left l hand sideare preferablyspread and fanned somewhatv more than those at the right hand -side of the V book D. l Consequently a second 23 isprovided which may, if desired,

which serves to spread out or fan the right hand sheetsofthebook D, this wheel also simultaneously iapplying glue to the over- 40 lapping margins of the sheets.

- effective means is provided for applying glue to the margins of-adjacent sheets soas to increase the bond between these sheets and the 45 adjacent sheets" thereby providin a much stronger book. and one which will e able to withstand inu'cli moreA rough usage than those vwhich .have heretofore been made by gluing .the sheets to 'thefcoven i While I have'gshown-and described but two embodiments of this invention, it is to be nn derstood thatj; itis capable of many modiiications.
